Forest at the edge of a Wide Valley
The following are among the first images I created using Planetside's Terragen 2 Technology Preview, which allows unlimited (global) landscapes and improved skies plus imported 3-D objects such as the trees in the following images.
From here the trees block most of the valley view.
Closer to the dge of the forest, the valley opens out to the twin peaks in the distance.
From a rougher edge of the valley one gets a more distant view of the trees.
